Abstract

A processing machine (10) for building an object (11) from powder (12) includes a build platform (32) that supports a powder layer (14), and an energy system (22). The energy system (22) selectively heats a portion of the powder (12) to generate a sintered portion (26) in the powder layer (14); and subsequently melts the powder (12) to generate a melted portion (28) in the sintered portion (26) of the powder layer (14) to form the object (11). The sintered portion (26) is smaller than the entire powder layer (14). Thus, only a selected, sintered portion (26) of the powder layer (14) is sintered, instead of the entire powder layer (14). A containment structure (611 B) can be concurrently formed to capture unsintered powder (29).
